As the conversation begins, what are the man and woman doing?

M: Did you take these pictures? They’re very good.
W: Yes, I think they turned out well, too. I like to take my camera with me wherever I go. That way, if I see something interesting, I can snap a picture of it.
M: Carrying a big camera around is too much trouble for me.
W: My camera is really small, though. Here, let me show you.
